  • Online Backup Exchange 2003

    Hi Guys,

    I have a question. I know when online backup (full and incremental) runs it will purge transaction log files after it finishes.

    I wanted to ask you all. Let say online backup starts at 8:00 PM and finishes at 4:00 AM now it will purge all the T Logs which were created and committed before 8:00 PM. Now here is where i need clarification. While online backup is running exchange continues to receive emails and continue to make T Logs. So the transaction logs created while the backup is running ... will they also be purged after backup finishes or they will be purged when backup runs next time
    Thanks & Regards

    The backup time is the time the job started. Therefore anything that occurs during the backup window will not be purged.
    You will also find that during a backup, Exchange also backups up at least one or two of the transaction log files to ensure consistency.
